Well I bit the bullet and got the M8T so should have it in a few weeks hopefully if this turns out and runs great I'll get the M5B as well, Hopefully it runs like the Speed when it run in properly. Any one else running the M8T how did you find it behaved during run in any dramas........

Don't have the M8T but I am running the MF5 in my truggy & just got my CQ5for my buggy & will be breaking her in so far my M5 has been doing me well all around motorgreat run time & holds her tune the M5 is a long stroke the CQ5 is a short stroke so I will be able to give the pro's & cons once I race it in 2 weeks

Sounds good, Im also looking the C5Q as Rocco on the Xray forums has been pointing me in that direction as well.... What pipe you going to run im chasing a Sirio 2013 for the M8T for starters but have also been looking at the Max or Nova pipe...

The sirio pipe is great for the Sirio or Sirio base engines & also perfect for Picco as for Nova based engines it's not the best pipe it has a tendency to cook the nova's I am currently using the Max power 2018 on the M5 & will be using the 2073 pipe on the CQ5 & it still needs some more breaking in

Just ran my Max power M5 today with 2018 pipe on eight restrictor nearly done with the break in process, the engine is very very smooth, and the runtime so far on 8 restrictor is 10m38s to a flame out. Temping on an empty tank at 253F.

Needles still fat as pickup is a bit slow, once tuned am guessing 12mins easy at 260F maybe pushing 13mins on 7 restrictor.

Anyone else running the 3 port MX 21? What do you think about it? A friend of mine is just finishing break-in and it sounds great and was easy to get a tune on. It seems to have great bottom end but we haven't put a race tune on it yet.

It took forever to break in, like the novas, duh, but I've been so used to my p5 that it seemed a little slow to me, even compared to my .21bf novarossi, but maybe it needs more track time, sometimes it takes a while, but no joke I really didn't like it, I would rather have a bf nova, IMO....Should I try taking out a head shim or something. It seemed like something was wrong, but nothing I could say is really wrong with it. I might need to just put that sucker back in my buggy and run it to really say one way or another.....It really is a pretty engine, and well made. Any advice guys....

Hey Jorge, we have been running a M5B, with a MX 28011 head button, MX 6-T glow plug, .7mm head shim stack thickness, 7.5mm restrict-or, Ninja medium header, and a 2073 pipe, 20% Byron's fuel. VERY impressive top-end, awesome driveability and 12 minute run time at lake park. If we could hook it up I would sacrifice some run time for OFF THE CHAIN/ ON-ROAD WORTHY power and put the 8mm in. Have not had any need to play with pipes. LET IT RIP
